+// What's the use of `padStart()` and `padEnd()` in JavaScript?
+
+// String padding is often needed to ensure consistent formatting.
+// Common examples in ServiceNow:
+//  - Padding numeric IDs with leading zeros (e.g., "INC000045")
+//  - Making export data columns align neatly
+//  - Adding placeholders to strings for integration formatting
+
+// padStart(targetLength, padString)
+//    → Pads a string from the start until it reaches the target length
+
+// padEnd(targetLength, padString)
+//    → Pads a string from the end until it reaches the target length
+
+// Example:
+// "1234".padStart(10, "x"); // → "xxxxxx1234"
+// "1234".padEnd(10, "y");   // → "1234yyyyyy"
+
+(function executeRule(current, previous /* null when async */) {
+    
+    let num = "1234";
+
+    // Pad the start with "x"
+    let padStartExample = num.padStart(10, "x");
+    gs.info("padStart result: " + padStartExample); // "xxxxxx1234"
+
+    // Pad the end with "y"
+    let padEndExample = num.padEnd(10, "y");
+    gs.info("padEnd result: " + padEndExample); // "1234yyyyyy"
+
+    // ServiceNow use case: format Incident number
+    let incidentId = "45"; // Example numeric part
+    let formattedIncident = "INC" + incidentId.padStart(6, "0");
+    gs.info("Formatted Incident Number: " + formattedIncident); // "INC000045"
